App privacy

For the Hue Daylight app. Last updated 5 October 2026. The website has its own policy on the Privacy page.

Hue Daylight switches Philips Hue lights on when clouds make the day too dark, and off when it clears. It is made by Rogeha Studio. It has no account and no server of ours: it works on your phone and talks to your Hue Bridge directly.

Who is responsible

What the app stores, on your phone

Everything the app keeps stays on the phone:

• your Hue Bridge's address, the key the bridge gave the app when you paired, and the fingerprint of the bridge's certificate;
• the rooms and zones you chose, which of them the app switched on today, and, if you keep rooms off while it's bright, which of them it is holding off, whether each was on when it last looked, and when it last looked;
• your location, as coordinates and the name of the town;
• each room's sensitivity setting, whether rooms are kept off while bright, whether the automation is on, the latest forecast, and a line about the last run;
• a technical log of what the app did, in Android's own system log on the phone. It holds no bridge key and no coordinates, and Android clears it by itself.

If your phone backs itself up to your Google account, Android may include these settings in that backup, under your Google account's settings. The bridge's key is always left out of it.

What leaves the phone, and to whom

• Your Hue Bridge, on your home network: the key and the commands that read and switch your lights. To tell a Hue routine from you, the app also reads your Hue routines and when your Hue switches were last pressed; it only reads them, and keeps none of it. This does not go over the internet. The connection is encrypted and accepts only the bridge you paired with.
• Open-Meteo (open-meteo.com, a weather service): your location, rounded to about 10 metres, to fetch the forecast, at most about once an hour. In Switzerland the forecast is MeteoSwiss's, served by Open-Meteo. When you search for a town, the name or postcode you type goes there too.
• Android's place-name service (on most phones Google's): your coordinates, only when you tap Use my location, and once for a location saved before the app showed town names. It returns the name of the town.
• Philips Hue's bridge discovery (discovery.meethue.com, run by Signify): only when you tap Find bridge. It answers with the bridges registered from your home network.

With any of these web requests your IP address reaches the service, as it does for every website. Their own privacy policies apply. The app has no advertising, no analytics and no crash reporting. Nothing is sold or passed on.

Permissions

• Approximate location, asked for only when you tap Use my location, to fill in your town once. Without it, search for your town instead.
• Notifications, asked for when you switch the automation on, to tell you when the app switched the lights on or off. The notifications are shown on the phone only.
• Internet and network state, to reach the bridge and the forecast.

The app works without location or notification permission.

How long data is kept

• On the phone: until you change it, tap Forget this bridge, or uninstall the app.
• The rooms the app switched on: until sunset each day.
• The Hue Bridge keeps a record of the app's key until it is removed in the Philips Hue app's or account's settings.

Deleting your data

Uninstalling the app removes everything it stored on the phone. We hold no data about you, so there is nothing to delete on our side.

Your rights

You can ask what personal data about you is processed, and have it corrected or deleted. Write to support@rogehastudio.com. You can also turn to the Federal Data Protection and Information Commissioner (FDPIC).

Children

The app is not directed at children, and we do not knowingly collect data from them.

Changes

If this policy changes, the date at the top changes with it. The current version is always at this address.
